Abstract

Femoral osteolysis associated with contralateral hip degenerative changes is a risk factor for ipsilateral periprosthetic femoral fracture. We report 5 comminuted proximal shaft fractures around loose femoral implants occurring in patients with both symptomatic femoral lysis and a painful hip on the other side. Our evolving strategy involves timely revision surgery once this pattern is recognized. Once fracture has occurred, emergent revision requires extensive medical evaluation, availability of long-stem revision implants, and appropriate instrumentation and allografts for fracture fixation.
